motor-0-position error beim Abbremsen aus 4-7,5 m/min

Hello PCW, tommylight,
Yes, I have switched to the optional Realtec Network Controller, because with the Intel i got triple as bad pings as with the Realtec when using it for the Mesa Card. (The Intel is very unstable indeed, Internet sometimes connects only with fixed IP, sometimes only with DHCP, that has cost me nerves the last weeks)

hanno@Linuxcnc-1:~$ lspci  | grep -i ether
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 04)
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
I try to find the DKMS driver, if you say this could help.
(oops, trying to load DKMS, I see "dkms ist schon die neueste Version (3.0.10-8+deb12u1)." But I can install/write the driver with r8168 new. I wait until I have done all the steps for that driver.

tommylight: ip a gives back:
hanno@Linuxcnc-1:~$ ip a

What does that mean in relation to my pings?

Thanks for your support!

If you have both Intel and Realtek MACs available, I would choose the Intel device for realtime.
 (especially if there are issues installing the DKMS Realtek driver)
 

Well, I have installed the DKMS driver r8168 and repeated the ping test and histogram. Ping is a little slower but base thread in the histogram is way better than before!

Here is my ip a and test of r8168:
hanno@Linuxcnc-1:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host noprefixroute
valid_lft forever preferred_lft forever
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0a:cd:00:00:1b brd ff:ff:ff:ff:ff:ff
inet 10.10.10.2/24 brd 10.10.10.255 scope global noprefixroute enp2s0
valid_lft forever preferred_lft forever
3: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

valid_lft forever preferred_lft forever
hanno@Linuxcnc-1:~$ lsmod | grep r8168
r8168 581632 0

What do you think about it?

Kind regards and thank you for your support!

BTW - I tried a lot to get the Intel going, but it was very frustrating and not successful, months ago, you gave me a lot of tips.
forum.linuxcnc.org/42-deutsch/53358-late...hlermeldung?start=30

tommylight, thank you for this tip! Yes indeed, I had the line sudo ethtool -C eno1 rx-usecs 0   on my Desktop to put it in the terminal each time after the PC starts. That helped a lot for the ping as I used the Intel NIC. So I gave Chatgpt the job to make a one-click file out of it, successfully. I can post it here asap, if I go down to my Linuxcnc PC tomorrow (Germany time)THe Realtec NIC is configured by start with coalescence=0, afaik.

PS: Below the file with double click function. delete the .txt and make it executable as a program. (ethool was the name Chatgpt gave it  )

 

Looks fixed to me.

Wish the LinuxCNC X86 image had the RealTek DKMS driver pre-installed
as the stock driver is NG
 

Hey guys, after several delays I got my machine running and I made my first part with it. First part, first problems. The locknut from my driven ball screw came loosened and I got a lot of backlash. I fixed that, then I had problems with my VFD (Hitachi WJ200), and had to send it to the service. Meanwhile, I used a chinese VFD (with filter unit in the line) , that worked fine, but last week I got the known problems with "motor-0-errors. Mostly if the x-axis stopped, turned around, then comes the error. Sometimes it runs several paths, then stopped again. That drives me crazy.
My latency is as good as before, I don't have lost packages, I don't know what to do with it.
Do you have any hints for me to change this problem? I put my actual HAL and INI here.

BTW - I don't understand that kind of error. What makes LCNC to give this error out? There's no connection to the motor's encoders, no feedback nothing what makes sense for me...

Tanks for any help!
Kind regards, Hanno
